You're likely referring to a specific type of adult-oriented vacation or resort. Maspalomas, located on the island of Gran Canaria in the Canary Islands, Spain, is known for its vibrant and open attitude towards sexuality.
Maspalomas has a section of its beach known as the "Dunas Beach" or "Maspalomas Beach," which has historically been associated with a more liberal and permissive atmosphere. This area has sometimes been referred to as a "swinger beach" due to its reputation for attracting individuals and couples who engage in open and consensual non-monogamous relationships.
